Yes, international workers can switch jobs in Luxembourg, but there are some rules to follow. In most cases, you must inform the Immigration Directorate, especially if you change employers or job roles. Some visa types may require you to apply for a new authorization to stay, depending on your contract and job category. Once you have long-term residence, changing jobs becomes much easier and does not require much paperwork. Employers in Luxembourg commonly hire foreign professionals, so job switching is possible as long as you follow immigration rules.
